DS started nursery today. He turned 2 in July. I'm starting to think I've made a mistake starting him at this age. I know lots of children start younger but I feel like we're in between. I stayed with him but he cried as soon as he couldn't see me. He's very shy and wary of new people and generally won't talk to anyone he doesn't know. He won't let anyone pick him up except me and DH. I thought this might do him some good but I don't know if I'm pushing him too much. Should we struggle through or wait til he's a bit older (3 maybe?) and he can understand more? I just don't know what to do for the best. He doesn't have to go, I'm studying at the moment so I'm at home but was going to use the time to study, I can take a few hours in the evening instead though.
